Abstract

Composition and films of linear ethylene polymers such as linear low density polyethylene containing up to about 3 weight percent of a blend of polyphenylene oxide and styrene resin exhibit excellent physical properties particularly impact strength.

Claims

exact text as granted — not AI-modified
We claim: 
     
       1. A composition comprising: (a) a linear ethylene polymer, and up to about 3 weight percent   of a blend of;   (b) 40 to 85 weight percent of a polyphenylene oxide and;   (c) 60 to 15 weight percent of a styrene resin.   
     
     
       2. The composition of claim 1 in which said linear polyethylene polymer is a copolymer of ethylene and a higher olefin containing 4 to 10 carbon atoms, having a density of 0.90 to 0.94. 
     
     
       3. The composition of claim 1 in which said linear polyethylene is a copolymer of ethylene and butene having a density of 0.90 to 0.94. 
     
     
       4. The composition of claim 1 in which said linear polyethylene is a copolymer of ethylene and hexene having a density of 0.90 to 0.94. 
     
     
       5. The composition of claim 1 in which said linear polyethylene is a copolymer of ethylene and octene having a density of 0.90 and 0.94. 
     
     
       6. A film comprising: (a) a linear ethylene polymer, and up to about 3 weight percent   of a blend of;   (b) 40 to 85 weight percent of a polyphenylene oxide and;   (c) 60 to 15 weight percent of a styrene resin.   
     
     
       7. The film of claim 6 in which said linear polyethylene polymer is a copolymer of ethylene and butene having a density of 0.90 to 0.94. 
     
     
       8. The film of claim 6 in which said linear polyethylene is a copolymer of ethylene and butene having a density of 0.90 to 0.94. 
     
     
       9. The film of claim 6 in which said linear polyethylene is a copolymer of ethylene and hexene having a density of 0.90 to 0.94. 
     
     
       10. The film of claim 6 in which said linear polyethylene is a copolymer of ethylene and octene having a density of 0.90 to 0.94.
